There are six described pathotypes of Escherichia coli that cause significant clinical illness in humans. Enteroinvasive E. coli (EIEC) strains have been shown to be separated into three phylogenomic clades. To add to a limited body of EIEC genomic data, we report two high-quality draft genomes representing different EIEC phylogenomic clades.

ABSTRACT Potential extraintestinal pathogenic Escherichia coli strains DP254, WH333, WH398, F356, FEX675, and FEX725 were isolated from retail chicken meat products. Here, we report the draft genome sequences for these six E. coli isolates, which are currently being used in food safety research.

ABSTRACT Escherichia coli is involved in the pathogenicity of metritis in cows. We report here the genome sequences of E. coli strains isolated at calving from the uterus, vagina, vulva, and rectoanal junction of a dairy cow that later developed metritis. The genomic similarities will give an insight into phylogenetic relationships among strains.

ABSTRACT Escherichia coli is one of the most common etiological agents responsible for clinical bovine mastitis. Here, we report the draft genome sequences and annotations of 113 E. coli strains that were isolated from Holstein cows with intramammary infections in Canada.

ABSTRACT Uropathogenic Escherichia coli serotype O4:H5 isolates (ATCC 700414, 700415, 700416, and 700417) were recovered from women with first-time urinary tract infections. Here, we report the draft genome sequences for these four E. coli isolates, which are currently being used to validate food safety processing technologies.

ABSTRACT Enterohemorrhagic Escherichia coli serotype O157:H7 is a major cause of foodborne outbreaks and hemolytic-uremic syndrome. Here, we report the draft genome sequences of three antibiotic-resistant E. coli O157:H7 strains isolated from feedlot cattle. These draft genome sequences will aid in the development of sequence-based tools for the detection of virulence and antimicrobial resistance genotypes.

ABSTRACTNeonatal meningitis-causingEscherichia coliisolates (SP-4, SP-5, SP-13, SP-46, and SP-65) were recovered between 1989 and 1997 from infants in the Netherlands. Here, we report the draft genome sequences of these fiveE. coliisolates, which are currently being used to validate food safety processing technologies.

ABSTRACT Strains of Escherichia coli exhibit diverse biofilm formation capabilities. E. coli K-12 expresses the red, dry, and rough (rdar) morphotype below 30°C, whereas clinical isolates frequently display the rdar morphotype semiconstitutively. We sequenced the genomes of eight E. coli strains to subsequently investigate the molecular basis of semiconstitutive rdar morphotype expression.

Draft genome sequences of Escherichia coli and Pseudomonas aeruginosa strains collected from clinical infections were used to determine the prevalence of newly emerging antibiotic resistance genes in Maine. Comparisons between cefepime-resistant and -susceptible E. coli strains and imipenem-resistant and -susceptible P. aeruginosa strains are being conducted.

ABSTRACT Escherichia coli bacteria commonly colonize the gastrointestinal tracts of farmed ruminants. Cattle are a well-recognized reservoir of zoonotic E. coli; we report here, however, the draft genome sequences of three diarrheagenic E. coli strains isolated from farmed red deer (Cervus elaphus) in the Manawatu region of New Zealand.

ABSTRACT The enterohemorrhagic pathotype represents a minor proportion of the Escherichia coli O103 strains shed in the feces of cattle. We report here the genome sequences of 43 strains of enterohemorrhagic E. coli (EHEC) O103:H2 isolated from feedlot cattle feces. The genomic analysis will provide information on the genetic diversity and virulence potential of bovine EHEC O103.
